* Shuffle around the wiggle crates This commit reorganizes the wiggle crates slightly by performing the following transforms: * The `crates/wiggle` crate, previously named `wiggle`, was moved to `crates/wiggle/crates/macro` and is renamed to `wiggle-macro`. * The `crates/wiggle/crates/runtime` crate, previously named `wiggle-runtime`, was moved to `crates/wiggle` and is renamed to `wiggle`. * The new `wiggle` crate depends on `wiggle-macro` and reexports the macro. The goal here is that consumers only deal with the `wiggle` crate itself. No more crates depend on `wiggle-runtime` and all dependencies are entirely on just the `wiggle` crate. * Remove the `crates/wiggle/crates` directory Move everything into `crates/wiggle` directly, like `wasi-common` * Add wiggle-macro to test-all script * Fixup a test
